1 surface picking
"The process of choosing which input surface contributes most to the output surface at a certain position on the output. Surface picking is often used with mouse operations to choose different actions in code that depend on which image you select. In cases where several images are alpha blended on the output point, the transform can use the alpha channel of each input sample to choose the input surface."
